--------------------------------------
Summary: Tuple cache needs to differentiate between consumed vs
produced runtime filters
Key: IMPALA-14275
URL: https://issues.apache.org/jira/browse/IMPALA-14275
Project: IMPALA
Issue Type: Bug
Components: Frontend
Affects Versions: Impala 5.0.0
Reporter: Joe McDonnell
The tuple cache needs to include information about consumed runtime filters
(e.g. a scan node receiving a runtime filter) to have a correct cache key. The
code is currently considering all runtime filters whether they are produced or
consumed. A hash join that produces a runtime filter will include that in the
hash. We should only include this for consumed runtime filters.
This only applies to mt_dop=0, because with mt_dop > 0 the runtime filter is
produced by the join builder fragment, which doesn't enter into the
calculations.
